Prosperity tries the souls even of the wise.
One may call the world a myth , in which bodies and things are visible, but souls and minds hidden. Besides, to wish to teach the whole truth about the Gods to all produces contempt in the foolish, because they cannot understand, and lack of zeal in the good, whereas to conceal the truth by myths prevents the contempt of the foolish, and compels the good to practice philosophy.
The soul is the captain and ruler of the life of morals.
While the body is young and fine, the soul blunders, but as the body grows old it attains its highest power. Again, every good soul uses mind; but no body can produce mind: for how should that which is without mind produce mind? Again, while the soul uses the body as an instrument, it is not in it; just as the engineer is not in his engines (although many engines move without being touched by any one).
It is not only spirits who punish the evil, the soul brings itself to judgment: and also it is not right for those who endure for ever to attain everything in a short time: and also, there is need of human virtue. If punishment followed instantly upon sin, men would act justly from fear and have no virtue.
If the transmigration of a soul takes place into a rational being, it simply becomes the soul of that body. But if the soul migrates into a brute beast, it follows the body outside, as a guardian spirit follows a man. For there could never be a rational soul in an irrational being.
The essences of the Gods never came into existence (for that which always is never comes into existence; and that exists for ever which possesses primary force and by nature suffers nothing): neither do they consist of bodies; for even in bodies the powers are incorporeal. Neither are they contained by space; for that is a property of bodies. Neither are they separate from the first cause nor from one another, just as thoughts are not separate from mind nor acts of knowledge from the soul.
Souls are punished when they have gone forth from the body, some wandering among us, some going to hot or cold places of the earth, some harassed by spirits. Under all circumstances they suffer with the irrational part of their nature, with which they also sinned. For its sake there subsists that shadowy body which is seen about graves, especially the graves of evil livers.
